Programmable Data Buffer

Features

The HSP9501 is a 10-Bit wide programmable data buffer

designed for use in high speed digital systems. Two different

modes of operation can be selected through the use of the

MODSEL input. In the delay mode, a programmable data

pipeline is created which can provide 2 to 1281 clock cycles

of delay between the input and output data. In the data

recirculate mode, the output data path is internally routed

back to the input to provide a programmable circular buffer.

• DC to 32MHz Operating Frequency

• Programmable Buffer Length from 2 to 1281 Words

• Supports Data Words to 10-Bits

• Clock Select Logic for Positive or Negative Edge

System Clocks

• Data Recirculate or Delay Modes of Operation

• Expandable Data Word Width or Buffer Length

• Three-State Outputs

The length of the buffer or amount of delay is programmed

through the use of the 11-bit Length Control Input Port (LC0-

10) and the Length Control Enable (LCEN). An 11-bit value

is applied to the LC0-10 inputs, LCEN is asserted, and the

next selected clock edge loads the new count value into the

Length Control Register. The delay path of the HSP9501

consists of two registers with a programmable delay RAM

between them, therefore, the value programmed into the

Length Control Register is the desired length - 2. The range

of values which can be programmed into the Length Control

overall range of programmable delays from 2 to 1281.

• TTL Compatible Inputs/Outputs

• Low Power CMOS

Applications

• Sample Rate Conversion

• Data Time Compression/Expansion

• Software Controlled Data Alignment

• Programmable Serial Data Shifting

• Audio/Speech Data Processing Video/Image Processing

Clock select logic is provided to allow the use of a positive or

negative edge system clock as the CLK input to the

HSP9501. The active edge of the CLK input is controlled

through the use of the CLKSEL input. All synchronous timing

(i.e., data setup, hold, and output delays) are relative to the

clock edge selected by CLKSEL. An additional clock enable

input (CLKEN) provides a means of disabling the internal

clock and holding the existing contents temporarily. All

outputs of the HSP9501 are three-state outputs to allow

direct interfacing to system or multi-use busses.

Video/Image Processing

• 1-H Delay Line of 910 NTSC, 1135 PAL or 1280 Samples:

- High Resolution Monitor Delay Line

- Comb Filter Designs

- Progressive Scanning Display

- TV Standards Conversion

- Image Processing

The HSP9501 is recommended for digital video processing

or any applications which require a programmable delay or

circular data buffer.
